Letters Patent No. 103,680, dated May 31,1870.

IMPROVEMENT CHM-LIIN-SEPAJATOIRS The Shedle referred to in these Letters Patent and making part of the same.

To all whom. it may conce-rn z Be it known that I, ORRIN STONE. of Ionia, in the' county of Ionia and State of Michigan, have invented certain new` and useful Improvements in Grain Separator-s, and I'do hereby declare the following to be a full, clean-and exact description of the same, reference being had to the accompanying drawing making a part of. this specification, in which- Figure l represents a perspective view of the separator from behind, showing the -movable section, with `the doors thereof, as also the back part ofthe tanning-mill shoe connected therewith.

Figure 2 represents a side view or longitudinal exhibit-ion of the separator, with the connections be- Y tween it and the machine, as also between it and the shoe aforesaid, as also the position, uses, and connections of the inclined rods.

Figure 3 represents a transverse view of the inelined rod and jourualbox, with the rod partially withdrawn, also the nut by which the movable scction is fastened to the journal-box.

Similar lettersot` reference, where they occur in the separate iignres, denote like parts of the separator and machinery connected therewith'.

The nature-of my invention will be more clearly understood by the following description:

It consists of a grain-separator, constructed in'two portions or sections, divided horizontally, the upper portion or section being stationary or fixed tb the frame-work of the separator, while the lower portion is movable'.

LIEhis movable section has two floors, the upper and lower. l

The upper floor is formed with transverse slats, with spaces between them, through which the grain falls onto the lower door.

The lower door is tight, with a series of notches, which carry the grain to the tanning-mill.

'lhe shoe of the farming-mill is attached to the movable section by means ot exible connections underneath, as shown in the .drawing so'that both move in the same; direction at the same time, and both are suspended on adjustable inclined slides or rods, the inclination being opposite to each other, so that, while the movable section goes down, the shoe goes up, thus eonnterbalancing each other.

The movable section and the shoe receive theirthe back part elevated, as shown in fig. 2.

b b represent the side piece of the movable section, with a portion removed to show the upper and To the frame-work of the separator are attached the metallic circles .f j, byscrews or bolts, as shown in the drawing.

Ilhe journal-box j is attached to the sides of the movable section by means ot'bolts and nuts, as shown at u.

rlhrough these journal-boxes the adjustable in` clined'rods g g pass, said rods being securely fastened in their places by means of the guards 7.', when attached to the metallic circles at h h and t' t'.

In the upper end of the guard at t' fi is a slot or opening, b y means of which the inclination ofthe rods may be regulated.

Io the lower floor ot' the movable section is attached a rod, l, connecting with the upright movable bar m, which has a series of openings,l by which to regulate the motion of the tanning-mill shoe o, and to which the upright bar m is also attached, by means of thc connecting-rod n, which passes over the fans at p.

Through the back posts of the separator-trame are inserted the adjustable inclined rods fr i', which are adjusted and secured by means of a wedge or wedges, as represented at q, said rods supporting the shoe o of the tanning-mill by means of the journal-box s.

t simply represents the nailing-spout, and

lc represents the space between the eoncavcmf the cylinder and the upper oor of the movable section, upon which the grain and straw fall as they leave thc cylinder.

Having thus fully described my invention,

That I claim therein as new, and desire to secure by Letters Patent, is-

1. A single movable section, b, (with two floors, 1 and 2,) suspended on adjustable inclined slides or rods g y. x

2. 'lhe tanning-mill shoe o, also suspended on adjustable inclined slides or rods 1* r, having their in clinations in opposite directions from the main slides g g, said shoe being attached to the movable section b by tleXible connections, as shown at fm., at, and Z in the drawing, thus securing au upward and forward motion in a straight line, instead of a circular motion, as here` inbefore represented, and for the purposes set forth.
